Application June 3, 1955, Serial No. 513,041

2 Claims. (Cl. 137-223) The present invention relates to new and usefulimprovements in air nozzles for use particularly in automobile servicestations and garages and has for its primary object to provide, in amanner as hereinafter set forth, novel means whereby substantially allof the usual opera tions involving the use of air under pressure such,for instance, as blowing, inflating tires, operating lifts and pneumatictools, etc., may be conveniently accomplished with a single combinationdevice.

Other objects of the invention are to provide a combination air nozzleof the aforementioned character which will be comparatively simple inconstruction, strong, durable, compact, highly efficient and reliable inuse and which may be manufactured at low cost.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure l is a view in side elevation of a combination air nozzleconstructed in accordance with the present invention;

Figure 2 is a top plan view of the device; and,

Figure 3 is a vertical longitudinal sectional view, taken substantiallyon the line 33 of Figure 2.

Referring now to the drawing in detail, it will be seen that theembodiment of the invention which has been illustrated comprises anelongated metallic body 5 of substantially the shape shown. Extendingvertically through the body 5 at an intermediate point is an air chamber6.

Extending londitudinally in the body 5 from the rear end thereof to thechamber 6 is an air inlet passage 7. The inlet passage 7 comprises anenlarged, threaded rear end portion 8 for permanently connecting a hosefrom a suitable source of air under pressure to the body 5.

The chamber 6 includes an enlarged, threaded upper portion 9 whichaccommodates a thumb valve 10. The valve 10, in the embodiment shown,includes a threaded metallic housing 11 which is screwed into theportion 9 of the chamber 6, said housing being open at its lower end andcomprising a seat 12. The housing 11 further includes, in its lowerportion, a multiplicity of outlet ports 13. Extending vertically throughthe housing 11 is a slidable rod 14 having a head 15 on its lower endengageable with the seat 12. A thumb button 16 is provided on the upperend of the stem 14. A coil spring 17 is interposed between the housing11 and the button 16 for engaging the head 15 with the seat 12.

Formed longitudinally in the upper forward portion of the body 5 is ablowing passage 18 which communicates with the upper portion of thechamber 6 on the outlet side of the valve 10. Thus, the valve 10controls the passage 18. The passage 18 terminates in an enlargedforward end portion in which a jet nozzle or tip 19 is threadedlymounted.

Also formed longitudinally in the forward portion of hired States Patent0 2,869,573 Patented Jan. 20, 1959 the body 5, below the passage 18, isan inflating passage 29 which communicates with the chamber 6 below thevalve 10. The forward end portion of the passage 20 is enlarged andformed to threadedly receive a chuck 21 which is engageable in the usualmanner with the inflating valve of a pneumatic tire.

The chamber 6 further includes a rearwardly angled lower portion 22which threadedly receives a suitable quick coupler 23 similar to thevalved chuck 21 for detachably connecting a hose to an air lift orpneumatic tool to the body 5.

It is thought that the operation of the device will be readily apparentfrom a consideration of the foregoing. Briefly, the valve 10 and theusual valve 24 of the chuck 21 are normally closed. Air under pressureenters the chamber 6 from the inlet passage 7. When it is desired toblow carbon, for instance, the valve 111) is opened to permit the air todischarge under pressure through the passage 18 and the tip 19. Theconstruction and arrangement of parts, it will be observed, is such thatthe valve it} may be conveniently opened with the thumb of the handwhich grips the body 5. To inflate a pneumatic tire, the chuck 21 isengaged with the valve stem of said tire in the usual manner. Foroperating an air lift or pneumatic tools, it is only necessary toconnect a suitable hose therefrom to the body 5 through the medium ofthe coupler 23.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described, andaccordingly all suitable modifications and equivalents may be resortedto, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A combination air nozzle comprising an elongated body having front,rear and intermediate portions, a transverse bore in said intermediateportion extending entirely through said body, an air supply passage insaid rear portion having continuous direct and unrestrictedcommunication at its forward end with said transverse bore and adaptedat its rear end for connection to a source of air under pressure, a pairof longitudinal air delivery passages in said front portion opening uponthe front end of the latter and with'their rear ends communicatingdirectly with said transverse bore, said transverse bore being ofgreater cross sectional area than those of said supply and deliverypassages, the forward end of one of said delivery passages having a jetnozzle therein, a manually operable spring closed valve assemblydisposed in one end of said transverse bore and controlling thecommunication of the latter with the air delivery passage of said jetnozzle, the other of said air delivery passages having continuous andunobstructed communication at its rear end with said transverse bore andhaving a valved tire valve chuck at its forward end, an air deliveryfitting mounted in the other end of said transverse bore and havingdirect, continuous and unobstructed communication with the latter.

2. The combination of claim 1 wherein said manually operated valveassembly and said air delivery fitting project laterally in oppositedirections from said body with said air delivery fitting being inclinedrearwardly of said body.
